Abstract | Rhesus monkeys (macaca mulatta) were infected subcutaneously with 1.0 x 10**4 to 1.5 x 10**4 metacyclic trypomastigotes of Trypanosoma cruzi (Colombian strain). Parasitological and immunological parameters were evaluated in these animals for periods of 1 month to over 3 years. a chagona was observed between the 3 rd and the 13th day after infection (a.i) and patent parasitaemia between the 13th and 59th day a.i.. Thereafter, parasites were demonstrated only by haemoculture and/or xenodiagnosis. Circulating specifc IgM and IgC antibodies were observed as early as in the 2nd week a. i. IgG levels persisted until the end of the expriment, but IgM antibodies were detectable nine months a. i. Haematological alterations comprised leucocytosis and lymphocytosis. Eletrocardiographic alterations were minor and transient, similar to those observe in non-lethal human acute Chagas' myocarditis. Myocarditis and myositis, characterized by multiple foci of lympho-histiocyte inflammatory infiltrate, were present in monkeys sacrificed on the 41 th, 70th and 76 th day but not in the animal sacrificed 3 years and 3 months a. i.. The results suggest that Chagas' disease in rhesus monkeys reproduces the acute and indeterminate phases of human Chagas' disease. | pt_BR |
